1. Choose a pond with good water quality, no pollution sources and little outside interference. Use moso bamboo to set up a bracket in the pond, and fix the corners of the net box on the bracket. Each net box set up a food table. Eels because of the habit of mutual carnivory, so the stocking specifications require basic consistency, generally 20 to 50 grams / tail.
2, eel stocking time should be selected in April, May, or August to September, in order to avoid the mid-May to July eel sexual maturity breeding period. The most suitable temperature for eels is 24 to 28 degrees Celsius.
3, feeding should be timed, eels day and night, in the afternoon 6 pm to 8 pm feeding is appropriate. The feed should be fresh, not put rotting and moldy feed. Feed should be washed before putting, each cubic meter of water and then 3 to 5 grams of salt immersion 10-20 minutes, and then rinsed with water before feeding. Generally choose freshwater small mixed fish, the daily bait quantity is 3%-5% of the total weight of eels in the net box.
4, artificial feeding, due to feeding a large number of feed, eels exclude feces easily contaminated water, so it is necessary to often refill new water to keep the water quality fresh. Spring 7 days to 10 days to change the water, summer 3 days to 5 days to change the water.
5, the net box should also be regularly disinfected, 10 grams of bleach per cubic meter of water, the whole pool splash. After stocking, the net box can be stocked with an appropriate amount of loach, the use of loach up and down the habit, play a diversion to increase the role of oxygen, but also to eliminate the eel residual bait. In the pond stocking a certain amount of chub to regulate water quality.
6, timely cleaning of the net box, remove excessive debris and attached algae, keep the net box inside and outside the water exchange smooth. The net box species placed water plants, water hyacinth, water peanut is good, for the growth of eels habitat to provide a good place. Transplantation of water peanut is best to remove the roots and wash in 5% salt water soaked for about 10 minutes to prevent locusts and other harmful organisms with the grass into the box.
7, eel seedlings in the box before the strict disinfection, especially in the eel prone to disease in July ~ September, every 20 days with 1ppm bleach sprinkled throughout the box, the discovery of sick eels timely isolation. Discover the disease, timely and symptomatic medication to minimize losses.
8, December every year, when the water temperature drops to below 12 degrees, eel feeding, growth basically stop. At this time, the eels in the net box will be harvested on the market.
